    7. Objectives, learning outcomes and obtained knowledge

    The course (together with the course entitled Digital Design 1) provides the students with all system level hardware knowledge required to the logical level design of microprocessor based digital equipment. The theoretical background is also widened through the solution of design problems during the classroom practices.

    Students successfully passing the course will:

    • learn the methods and practices in the design and analysis of microprocessor systems.
    • obtain detailed understanding of a simple microprocessor, its common peripherals and its assembly language
    • be able to quickly understand the usage of other microprocessors.

    Interfacing basic peripheral units (LCD displays, switches, pushbuttons) to a microprocessor bus. software routines for handling such peripherals.

    Overview of modern memory types (NVRAM, FRAM, MRAM, SDRAM, Flash). Internal organization and interface of high capacity memory modules.

    Microcontroller architectures. The features of a common microcontroller family. Design example with microcontrollers.

    9. Method of instruction
